Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed
Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed
Department of Anaesthesia
Laparoscopic surgery has several advantages over conventional surgery for the patient. An increasing number of diagnostic and surgical procedures are being done laparoscopic not only in adults but also in paediatrics patients. In addition to the routine anaesthetic considerations for any surgical patient, the choice of the anaesthetic technique in patients undergoing laparoscopic procedures should consider the patient's underlying cardio respiratory functions induced by the pneumoperitoneum and carbon dioxide [CO2] insufflations. This article describes the physiological alterations induced by laparoscopic procedures in children and the anaesthetic implications of laparoscopic in the paediatric patient population.
The Role Of Prophylactic Intra-Aortic Balloon Pump Counterpulsation (Iabp) In Emergency Non-Cardiac Surgery, Khalid Samad, Fauzia Anis Khan
The Role Of Prophylactic Intra-Aortic Balloon Pump Counterpulsation (Iabp) In Emergency Non-Cardiac Surgery, Khalid Samad, Fauzia Anis Khan
Department of Anaesthesia
Patients with recent myocardial infarction (MI), congestive heart failure, severe angina, or uncorrected multivessel coronary artery disease are at increased risk of cardiac complications after urgent major non-cardiac surgery. Although invasive haemodynamic monitoring and preoperative optimization of cardiac status may lead to some reduction in the rate of perioperative cardiac events, the mortality from such events still remains high. The use of an intra-aortic balloon pump (IABP) may play a role in such patients by improving the function of the injured heart. We report our experience with the use of perioperative IABP in a patient with unstable angina and recent …

Apache Ii Score As A Predictor Of Length Of Stay And Outcome In Our Icus, Shahla Siddiqui, Saad Ahmed, Roshan Manasia
Apache Ii Score As A Predictor Of Length Of Stay And Outcome In Our Icus, Shahla Siddiqui, Saad Ahmed, Roshan Manasia
Department of Anaesthesia
The APACHE II (acute physiology and chronic health evaluation) is used widely for predicting probability of hospital mortality and length of stay in the ICU. APACHE II forms were available to all ICU residents within 24 hours of admission, and a score was assigned to them. Based on our results the APACHE II score has reliably predicted an outcome of the least amount of length of stay (LOS) in the ICU as well as a 100% probability of being shifted out of the ICU for a score of < 10 (according to international benchmarks). This reliable scoring system can be used for predicting mortality and length of stay and therefore, resource allocation, antibiotic use and ethical decisions regarding counseling families about end of life decisions--all within 24 hours of admissions.

Perioperative Anaesthetic Management Of A Patient With Relapsed Aplastic Anaemia, Aliya Ahmed, Abdul Monem
Perioperative Anaesthetic Management Of A Patient With Relapsed Aplastic Anaemia, Aliya Ahmed, Abdul Monem
Department of Anaesthesia
Aplastic anaemia occurs due to failure of blood cell production by bone marrow. All blood cell counts are low. Untreated patients may die within one year mainly due to uncontrolled infection due to neutropenia. Anaemia and thrombocytopenia cause troublesome symptoms and necessitate frequent red cell and platelets transfusions. Surgery poses a very high risk for these patients because of the several complications that can occur in the perioperative period. In this paper we report on a patient with relapsed aplastic anaemia who was optimized preoperatively and underwent a total abdominal hysterectomy under general anaesthesia.
